摘　　要：We have found an incorrect formula to estimate the root mean square(rms)amplitude of the molecular vibration in the molecular optomechanics systems reported by J.Liu et al.[Photon.Res.5,450–456(2017)[CrossRef]].In contrast with common optomechanical systems,the equilibrium position for molecular optomechanics systems used in the letter cannot be achieved by the equipartition theorem.Here,we achieve the effective temperature of molecules and then provide a corrected formula for the estimation of the rms amplitude of molecular motion.Using defined effective temperature into our new formula,we show that the minimal measurable force is(𝐹≈1.7×10^(−14) N),which it is 1 order bigger than the result of the main paper,and it is also in accordance with numerical calculation through the Lindblad master equation.
